Since I have no coding background before, I have to start from zero.

Just because a lot of people have been super busy IRL lately, it would be best
to look at the POV-Ray wiki
http://wiki.povray.org/content/Main_Page
and the "Search" part of this newsgroup and the "F1 help" while running POV-Ray
to familiarize yourself with the basics and some of the commands ("directives")
you are likely to use.

Otherwise it's a little too much like "do my homework for me".

you have 162 particles?
define "the central point of the particle" as POV-Ray's origin, and there ya go.

There's likely hundreds if you search the newsgroups for read write data array
etc because over the past 20+ years people have written tens of thousands of
scenes using these very same basic data structures.

Post a copy of your actual data, and that would help us to see exactly what
you're working with.
